The utility model content
Technical problem to be solved in the utility model is to overcome the defective of prior art, and a kind of USB flash disk module that can expand other functions is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of USB flash disk module is provided, comprise printed circuit board (PCB) with first surface and second surface, be located at the memory circuit of described printed circuit board (PCB) first surface and cover on described memory circuit and it is packaged in packing colloid on first surface, the second surface of described printed circuit board (PCB) is provided with the first metal contact piece group that meets the standard USB interface agreement, the second surface of described packing colloid and/or described printed circuit board (PCB) is provided with groove, is placed with the expanded function parts in described groove.
Preferably, described expanded function parts are magnetic part.
Further, the second surface of described printed circuit board (PCB) is provided with the second metal contact piece group that can test described memory circuit, and described the second metal contact piece group is electrically connected to described the first metal contact piece group.
Further, described the second metal contact piece group is electrically connected to functor.
Preferably, described functor is LED light.
In the utility model, offer the groove of placing the expanded function parts on the second surface of packing colloid and/or printed circuit board (PCB), place again the parts with expanded function in groove, make the use of USB flash disk module be not limited to store this single function, and can expand other function.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
as shown in Figures 2 and 3, the USB flash disk module that the utility model provides, comprise the printed circuit board (PCB) 100 with first surface 110 and second surface 120, be located at the memory circuit (not shown) of described printed circuit board (PCB) 100 first surfaces 110 and cover on described memory circuit and it is packaged in packing colloid 200 on first surface 110, the second surface 120 of described printed circuit board (PCB) 100 is provided with the first metal contact piece group 121 that meets the standard USB interface agreement, the second surface 120 of described packing colloid 200 and/or described printed circuit board (PCB) 100 is provided with groove 300, be placed with expanded function parts (not shown) in described groove 300.In the present embodiment, offer the groove 300 of placing the expanded function parts on the second surface 120 of packing colloid 200 and/or described printed circuit board (PCB) 100, the parts that have expanded function in the interior placement of groove 300 again, make the use of USB flash disk module be not limited to store this single function, and can expand other function.
Referring again to Fig. 2, in the present embodiment, only show groove 300 and be located at a kind of structure on packing colloid 200.
Preferably, the described expanded function parts that are placed in groove 300 are the magnetic part (not shown).Magnetic part is arranged at groove 300 when interior, and the USB flash disk module namely has magnetic attraction like this, and when the shell of finished product USB flash disk module was also made for magnetic material or is provided with magnetic part, the USB flash disk module just can firmly be adsorbed with shell, avoids shell to lose.Simultaneously, a plurality of USB flash disk modules are placed, also can be utilized mutual magnetic attraction to be placed in together when taking in, and avoid being scattered.Certainly, the magnetic part here also can adopt does not have magnetic, but can replace with other parts that magnetic part is inhaled mutually, and as iron block, at this moment, the shell that need to coordinate with the USB flash disk module has magnetic force and gets final product.In the present embodiment, utilize magnetic part to expand the easy placement of USB flash disk module, the function of mutual attraction, certainly, the expanded function parts also can be the parts with other function, and when it was positioned over groove 300, being complementary with groove 300 structures can fixedly secure it to get final product.
With reference to Fig. 3, in the present embodiment, the first metal contact piece group 121 comprises four metal contact pieces 1211, and the setting of these four metal contact pieces 1211 meets the USB2.0 agreement, it is electrically connected to memory circuit on first surface 110, is used for setting up data with external host device and is connected.Certainly, the first metal contact piece group 121 also can be arranged to meet the USB3.0 agreement herein, is not restricted herein.Simultaneously, the second surface 120 of described printed circuit board (PCB) 100 is provided with the second metal contact piece group 122 that can test described memory circuit, and described the second metal contact piece group 122 is electrically connected to described the first metal contact piece group 121.Because the first metal contact piece group 121 can only be for the USB interface place, can not expand other functions, and add the second wafer group 122 on the second surface 120 of printed circuit board (PCB) 100, can test by 122 pairs of described memory circuits of the second wafer group on the one hand, on the other hand can be by the second wafer group 122 other functions of expansion.
Further, as shown in Figure 4, described the second metal contact piece group 122 is electrically connected to functor 400, can realize its expanded function.
Preferably, described functor 400 is LED light.Like this, connect LED light by the second metal contact piece group 122, can judge exactly the duty of USB flash disk module, be beneficial to the user and experience.
These are only preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
